This ultimately uplifting tale of perseverance in the face of love and loss begins in the suburbs of an unnamed city in contemporary South Korea. Tragedy strikes when the father of sisters Nana and Sora is killed in a factory accidents. The compensation money is sequestered by their relatives, forcing the now impoverished sisters and their mother, Aeja, out of their house and their former lives.

The principal argument of Terence Roehrig’s new book is that the United States will not and should not use nuclear weapons to defend Japan or South Korea. The US nuclear umbrella, he contends, has been little more than a bluff because the threat to use nuclear weapons, even in response to a nuclear attack, is not credible or necessary.
